A few weeks ago, I headed out for a walk with Bob and Heidi on a warm day. Left my jacket at home. No bags. You know the moment — the dog squats and you are standing there with nothing. That was the day I decided I really need to design the CollarPod. I have had a few requests for something simila

It's been a while since I posted an update here, and I have a lot to share. Between some personal health stuff that's now well behind me and a few months of heads-down designing and growing (literally — more on that in a moment), I've been quieter than usual on the posting front. But the design wor

This year I decided I’m growing hot peppers properly 🌶️ Living in a colder climate means they need a long head start indoors if you want strong plants and a good harvest. My end goal is actually to smoke my own jalapeños in the smoker and turn them into homemade chipotle peppers — which means I ne

I’ve just released a brand new design called **STEPH – the Screen Top Edge Phone Holder**, along with a major mechanical update to my original **Phone Multi Widget** (now version 1.5). STEPH is a compact, print-in-place phone holder that mounts on the top edge of laptops, flat monitors, and tablets

This week I’m excited to share something that’s been simmering for a while — a pair of complementary designs that solve two parts of the same problem: messy workspaces and the scattered essentials that live on them. Why I Built This Between multiple monitors, phones, tablets, and all the adapters t

This week, I have posted my new Logical Wall-Mounted Spool Storage system that solved a massive problem for me. Sure, there are lots of spool storage systems out there and some really great ones. But I had my own specific criteria, like I wanted it to allow me to see all my open rolls of filament

I have reworked my super-thin locking system into a re-programmable combination lock, which is only 2mm thick. The entire case is printed in place with the tumblers and detent springs printed as compliant components incorporated into the case—the only other parts needed are the numbered dials, the

This is one of my favorite designs for a handful of reasons, but not the least of which it is super fun, and I designed a relatively complex (at least for me) lock and puzzle system in a 2mm layer that lies at the bottom of a box. The false bottom of the box is transparent'ish, so you can see the

I just posted a new version (2.0) of my StashHanger concept. It is a significant upgrade to the original version. This 100% printed, snap-together design allows you to hide things in a coat hanger. And, the StashHanger 2.0 folds into itself for storage and travel. A fun unconventional hiding pl

This week, I have posted my new modular crate system. There is a starter version of it posted here. I began designing it as a new version of my previous freezer crate, but in the end, it is just a really great multiple-purpose storage crate which you can use in your fridge, freezer, pantry or on

A year after designing and releasing my first pop-open drain strainer, I finally got the design inspiration I needed to make it way better. This new drain strainer (the "Drainer) is just way better. It is stronger, more durable, easier to open and easier to keep closed. It drains better and has

I think this is another pretty fun one... the Tablet Turret is an articulated tablet stand that is adjustable and turnable. It works really well for a desk top, workbench or kitchen counter. But, what's more, it is a really good and educational demonstration of design techniques used in 3d printi

I have just posted a couple of new wasp trap designs that fit onto 2L PET bottles and mason jars.  The main impetus of these traps is making them much bigger than many of the alternatives out there.  Bigger serves a few purposes, but mostly makes it a more visible target for wasps and giv

This week I have posted my DrinkColder and it is one of my all-time favorite contraptions.  It is really quite simple but very entertaining to play with.  Everyone I have shown it to has wanted one. It is a self-closing, gear-powered can holder that opens automagically.No springs. No elec

This week I have posted what I think is a first... The GearBin, a mechanical binary locking system which is a super fun and nerdy lockable container but also a great teaching and learning tool. The 16-bit lock is organized into nibbles for quick and easy conversion to hexadecimal so you can save

I am super happy with my design this week, GearBin™, as it has been a long time in the works and it works really well. GearBin™ is a fully 3D printable mini trash bin with a gear-powered lid and fold-in liner frame. It uses standard dog waste/poop bags as liners. No glue, no screws—just print, sn

I feel like I have pretty much ridden the CardDock train as far as it goes (time will tell).  But driven by the tremendous interest in it and user requests I have added many more CardDock models for all sorts of playing cards and also even business cards and credit cards.  There might be

This would not normally be worth a posting here but I wanted to bring to everyone's attention that I have revised this today after posting it a day or so ago. Someone pointed out to me that the filament anchoring holes (for winding filament - should you want to) should be parallel to the wound fil

In the fun and card games category, this week I released my self-aligning card deck holder.  It is a novel way to keep your playing cards stacked neatly but is also a case and a stand to keep the cards off the playing surface (you know… spilt beer and the like). The lid can also serve as a di

I am really really happy with this week’s post, the SpringDock phone holder.   It is a 100% 3D-printable, snap-together phone holder built with compliant spring grippers that hold your phone securely with a simple squeeze-and-release motion.  That is mounted onto a set of articulated arms

Just in time for Easter, check out this large 4-digit alphabetic programmable combination locking egg. With more than 456,000 possible combinations, this fun egg could be part of any Easter egg hunt event. Files are available here... https://than.gs/m/1307255 ,

This week I have posted my most complex mechanical contraption.  It is a fully printable (no hardware required) dispensing mechanism.  It is currently configured for dog biscuits, but it could be used for a wide range of things.  I just don’t know what!  But it is fun and I thin

While I am putting the finishing touches on a major design project to be released hopefully this week, I have posted a favourite of my wife’s and also done a bunch of catch up of some backlogged design revisions.  But first the lipstick….   Lipstick on the wall - This is a simple design t

This weeks post is a solution to a small life problem for me and hopefully it will benefit others. When I occasionally want a Tylenol in the middle of the night I regret the noise and activity that goes along with it and worry it will wake my wife. With this handy contraption, I can get a single

So, it has been a few weeks since my last post here, and during this period, I have spent a lot of time learning to design compliant components so that I can better implement them into designs going forward. Compliant compoenents are an area that our 3d printers excel at and create so many opportu

This past week, I’ve been busy updating, reorganizing, and launching my new ClampDock system! Introducing ClampDock The ClampDock is a 3D-printed, snap-together modular system for attaching accessories to a table, desk, or shelf. It installs and removes quickly, and its accessories snap on and off

If you haven’t started printing filament samples yet (like I hadn’t), now is a perfect time to start with my new modular filament sample (swatch) system. It scales up as you print more samples, so you’ll always have a neat and tidy way to organize them. Why should you print filament samples?Over ti

I dislike wearing wet gloves and I need gloves frequently during the winter months. Walking my dogs multiple times a day and playing ball, the gloves just do not have time to dry out. So i created the glove dryer and it works fantastic. In my experience as much as 4 times faster than just leavi

This week I posted my USB Drive Rack with a radial push-push style mechanism to open and close it. It is a fun way to elevate your sometimes forgotten favourite USB drives. I have to admit my concentration dropped a little and I accidentally posted it initially missing one part (the Receiver) t

This is my biggest design project to date and also the funnest ones. If you or someone you know loves very challenging discovery puzzles check this out! Of course I have to keep the details very limited and available only to those who download the puzzle to prevent the solution to the puzzle bei

I have just posted an awesome eyewear stand system. You can use it for a single pair of glasses or as many as you want. They snap together to form a structure that is stable, compact and convenient for the desk, nightstand or TV table. If you have and use eyewear you will be sure to like these.

Even though it is a little late for Christmas this year, I could not help but make this modified version of my previously release tree balls (https://than.gs/m/1217763). These are numbers 00 through to 24 and make a fun way to add a twist to your Christmas tree. Available here... https://than.gs

As I am sure you know by now, I am not much for ornamental designs but I could not resist making these ornamental tree balls functional. These balls are beautiful when printed with a glistening filament and yet much more... They fold (collapse) down and nest together for more compact storage at

This week I have posted a super fun lockable gift box. The gift box features a 4-dial combination system, with each dial offering numbers from 0 to 9, allowing for 10,000 unique code combinations. The code is fully customizable, making it both secure and versatile. The idea is you can give someone

Looking for a fun and unique 3D-printed project? My latest design is here—a puzzle gift box that you unlock by spinning it! The lid is secured with four floating latches that rely on centrifugal force to release. Until all the latches are pushed outward at the same time, the box remains securely lo

This week I brought the folding ball to life and I think it is super fun but also functional. Cats, dogs, kids and the kid in all of us will like it. I am working on some variants (a lighter one and a stronger one) but try this one out I think it will always be the best. Please check it out! Als

My latest to the gaming category is a new approach to crib board design intended to be more useable and more durable. If you love Crib, give this a try. Also, I have uploaded a sleek and effective snap-together eyewear case that will help to protect your eyewear. Print the 2 parts and snap them t

This week I have posted some access doors. I know not everyone needs these but when you need one this is the best one available (IMHO). In my case, I wanted to create an access opening to our water shutoff valve which is in the crawlspace and not easily accessible. This through-wall access door

One of my family members recently had shoulder surgery and as a result lost temporary use of an arm. She wanted to play cards to pass time while recovering but needed a card holder. There are plenty of them out there but I couldn't find any that were compact and adjustable. This design is all th

A 100% 3D printed knife seems unlikely to be successful (at least in plastic) but it actually works. Of course, not as well as a metal knife but for specific applications a plastic blade can get the job done. Plus the design is cool and novel. I am using it for cutting packing tape on packages t

This week, I've posted some AirTag holders designed to help you keep track of your AirTag inside a backpack, luggage, tool bag, or similar items. The idea is to clip it to a specific spot so that when you need to find it, you know exactly where it is (or where it should be). I've also shared a larg

It turns out that a 3D printer with AMS or multi-filament capability is excellent at creating high quality graphics and in this case signage. I have just posted the first batch of my utility signs and will be posting more in the future. If you want a specific sign that is not posted please send m

Free again for a limited time as part of the Thangs 4-year anniversary "throwback" celebration is the newer and improved pop-open drain strainer with pick-up knob. Still available in 2 sizes. Pull this drain strainer out of your sink and hold it over the waste bin, squeeze the sides, and it pops o

This past week I have posted a herb stripper for those that grow their own herbs. This is a great little device for harvesting garden herbs for drying before winter comes. And, it will save your fingers from changing colours (those that have done it know what I mean). I also posted a belt hanger

This week I have posted 3 new designs (so far).... A print-in-place folding door wedge which I think is novel and pretty practical (if you need a door wedge from time to time).   A print-in-place locking USB cable clasp.  This is kind of a companion product to the theft deterrent I posted

This week I have posted a charger cable theft deterrent because I am tired of those cables going missing. Now when you leave your USB cables unattended you can create a small barrier to someone taking them. This version is a low-security device but could be enough to deter theft. I am also worki

This week I have posted a melon cutter titled "Fruit Punch". And, my Wine Stackers to organize those wine bottles you have lying around waiting to drink. The Fruit Punch turned out so well I thought I better post it. My wife wanted it to make some fruit platters for a special event. They add a

I have posted a soap tray system I have been working on for some time. While it is probably not for everyone, if you need more space in your shower this could be of interest to you. So far I have soap trays and a razor holder but I can expand the system to other components. And, everything is sn

A very productive week for me, in the last 48 hours I have posted the following: A modular snap-together system for managing keys A remake of the classic magnetic key hider A drink coaster with a sunshade A new XL (extra long) version of my folding scalpel designed specifically for #60 blades, and

I have posted 4 designs this week all in an effort to get through my backlog of designs. Since it is summer... a dog ball carrier designed for Bob (he is ball obsessed). And, also three golf accessories including a ball and tee carrier. These designs will only be free for this week so please

I have posted two new designs again this week, the first one is an awesome addition to any kitchen... a pop-open sink drain strainer. Most of us have traditionally used a metal strainer that you have to slam or bang into the waste bin to empty it. This pop-open strainer opens on your command (or

As you may already know, I released two designs for this week and I only mentioned one of them in my previous post. I really did not expect that the backup TP holder would be so successful. But, hey, I needed it so it makes sense a lot of other people need it too. I am writing this post now to

In the "fun but somewhat useful" this spinning pen holder is a lot of fun (if you like to fidget). Of course, it holds pens but it spins effortlessly and silently making it a great desktop companion. Give it a try! I deleted my initial upload of this as it seemed to not be downloading well. Ple

This week I have posted 2 designs simultaneously, an updated and significantly improved version of my folding scalpel and also a fun "StashHanger" which provides a secret storage compartment as part of a clothes hanger. I created the StashHanger out of need. I wanted to have a simple and conveni

I just added a No.3 scalpel handle to my "Scalpel Station Widget - with Auto Blade Removal and Capture". It does not work as well as the original #4 handle, but I did get the #3 handle to work with some blades I have.  So if you have blades for the #3 handle please feel free to give this a tr

I just posted my latest widget... the scalpel holder desktop station with integrated automatic blade removal and blade capture.  It has blade storage and a blade insertion tool.  It is a fun contraption for displaying your 3D printing skills.   It makes the perfect desktop device fo

I have been working on these tool blocks for a long time and I finally made time to get them posted. Their single purpose is to get those awkward hand tools organized and at the same time keep them handy for use at your workbench or desk. Let me know if you need any other sizes!

Today I launched some memberships to address a few things... 1. Addressing the demand I have had for commercial licensing, 2. Giving me a mechanism to have paid models (which has become critical to the Leagues) and lastly, 3. Hoping to create an alternative method for support from those who can a

This week I made a print-in-place folding scalpel which I find to be an excellent detail knife that beats out all my other "exacto" style knives. Best for detail work (not heavy duty). But the real excitement of this design is printing in place a very tight tolerance that has virtually no play in

When my wife suggests I design and print something... I always do it. This is one of those tings. Drink markers/charms that can be used on any kind of glass just makes sense. Here it is. I am making this free for 1 week to try to stimulate more downloads and likes to help with the contest compe

I just posted what I think is the world’s first gimballed wine holster.  And, it is 100% printable with no hardware, fasteners or adhesives required.   It is basically a companion to my beer holster (BevvySteady3) but unlike the offset-gimbal of that design, this one is centre-gimballed a

Sometimes it is nice to make a really effective simple design that gets a lot of use.  This utility knife handle and case is one of those things for me.  I have been using it now for some time and it is awesome.  I hope you find it useful too.  If you need it adjusted for a diff

About 21 people downloaded my StashCan 2.0 that I posted yesterday before I realized I uploaded the wrong STL file for the Can. The thread at the top is wrong. I have deleted that initial post and reposted the entire assembly with the corrected Can file. The correct can file is titled "StashCan
